How many miles on the car?
Is this the outside door handle and is it chrome and not painted?
This is a very common problem on these cars and only happens to the chrome handles. The problem is the handle is broken. The fastener that holds the handle to the door breaks and comes out of the handle which causes the handle to be loose. To repair this, the handle has to be replaced. Since this is such a common problem, most dealerships will "goodwill" this repair since you are out of warranty. If you have less then 75k miles the dealership should do this repair for no charge. If you have high mileage, then you may have to pay for the repair. This is a repair you can do at home, the handle is held in with 3 bolts, you just have to remove the inside door panel.
